The invention relates to a carbon fiber foam sandwich composite flame-retardant material and a preparation method thereof, and belongs to the technical field of fire prevention and heat insulation. The material comprises a foam core material, a carbon fiber cloth layer is laid on the outer side of the foam core material according to a set sequence, a fireproof material layer is laid on the outer side of carbon fiber cloth according to a set sequence, and the carbon fiber cloth layer and the fireproof material layer are filled with epoxy resin. The volume ratio of the epoxy resin is 50-55%; in the carbon fiber foam sandwich composite flame-retardant material, the epoxy resin accounts for 50-55% by mass; the fireproof material comprises one or more of a fiber material and a porous material; the carbon fiber cloth layer comprises a plurality of layers of carbon fiber cloth. The fireproof fiber material layer is additionally arranged on the outer side of the carbon fiber cloth layer, so that the flame retardant grade of the product can be further improved on the premise of fully retaining the advantages of 94V0-grade epoxy resin; and the method is suitable for a VARI forming method, and efficient batch production of high-flame-retardant-grade products can be achieved.
本发明涉及一种碳纤维泡沫夹芯复合阻燃材料和制备方法,属于防火隔热技术领域。材料包括泡沫芯材,泡沫芯材外侧按照设定的顺序铺设有碳纤维布层,碳纤维布外侧按照设定的顺序铺设有防火材料层,碳纤维布层和防火材料层中填充有环氧树脂;环氧树脂所占体积比例为50~55%;碳纤维泡沫夹芯复合阻燃材料中,环氧树脂所占质量比例为50~55%;防火材料包括纤维材料和多孔材料中的一种或多种;碳纤维布层包括多层碳纤维布。本发明在碳纤维布层外侧增加防火纤维材料层,能够在充分保留94V0级环氧树脂的优势的前提下进一步提高产品的阻燃等级;且适用于VARI成型方法,能够实现高阻燃等级产品的高效批量生产。
